Or with regards to the modules loaded in the initrd, 
change /etc/mkinitrd/mkinitrd.conf to have the line
    MODULES=dep
instead of =[all,most] and then regenerate the initrd.

That's what I've done anyway and it works great. One issue with newer kernels 
is that is seems to load all IDE drivers regardless since they aren't yet 
tagged as unloadable (shows [permanent] in lsmod). How can one indicate to 
initrd (or yaird) selectively which ide modules to load?
